The RTX 3070 Ti may not be the top-tier GPU that it once was, but it is still an affordable and worthwhile GPU that shouldn’t be dismissed from your next PC build. For the ideal computer component compilation, it’s recommended that you choose one of the best PSUs for RTX 3070 Ti PC builds: these have all been chosen as proven high-quality 3070 Ti recommended PSUs, that save you money in both the short and long-term with high energy efficiency and great upfront value.

We’ve compiled this buyer’s guide with that in mind: choosing budget and energy-conscious options that all meet the RTX 3070 Ti PSU requirements with ease. Whether this is your first PC build and you’re looking to save money, or you are reconfiguring an existing scheme, we’ve got you covered with our picks for the best power supply for the RTX 3070 Ti!

RTX 3070 Ti PSU requirements

Though not quite as low as its sibling, the RTX 3070, the 3070 Ti recommended PSU starts at a reasonable 750W. This is relatively low by modern standards, so we recommend adding a little bit of wattage for getting the most out of your 3070 Ti power supply. As such, most of our choices today will account for a higher-than-minimum wattage.

That said, it is possible to use a 650W PSU for 3070 Ti PCs, but only with very low-specification components. If you are looking for a low-end PC, make sure to use a PSU calculator to get the correct wattage – though bear in mind that the same reasoning applies in investing in a higher-wattage PSU!

This is one of our favorite options for budget PC builders, as there are a number of variations to suit different financial situations, whilst also having a high overall internal quality.

Though the semi-modular design makes installation more difficult, and you won’t get the longevity of higher-wattage models, the GF2 strikes an excellent middle ground between price and quality as a PSU for 3070 Ti PC builds!
